Hi,
I have a question about Generics,like this
public static void main(String[] args) {
ArrayList<String> list = new ArrayList<String>();
list.add("abc");
printName(list);
}
public static <T> void printName(List<T>list) {
System.out.println(list.get(0).getClass().getSimpleName());
}
public static <T> void printName2(List<T>list,Class<T>cls) {
System.out.println(cls.getSimpleName());
}
If the list is empty,the method "printName" is in error.
exclude this two methods,is any other way to get the Type of the elements of
List?
Thanks for your help.
